For those achievement hunters like me who want to get the 100% on this game. Hope this guide helps you to get these two tedious achievements in a faster way.

First things first. I recommend to leave both achievements for the very end after beating the game since you will be killing monsters as well as using skills in combat every time you enter to a quest and make progress along the way. In the end-game you will have all the resources and buildings to max levels so you can level up any student to max level in just seconds and no problems to make things faster.

Legendary Slayer

Defeat 5000 monsters



Very simple. Get any student (preferably a Mage and promoted to have more MP) to the highest level learn the skill Serpent's Tongue from the Magic tree skills.

You can send students to do errands and skip to the next months without having to do any quest manually and level them up in no time - that's why i also recommend to do this after end-game.



This skill deals 150% magic damage to all enemies which will help to make things faster.

When you have the ability set up on your student and ready to go next step is how to grind.
Make sure to equip the skill from your student's active skills!

Simply go the first region Plains of Perun and select the very first quest which is about exploring the dungeon. Make sure to pick the student that has the skill Serpent's Tongue equipped and on the middle of the three students to be the main character you control

• Here is the deal. Go to this area where you see these 5 Giga Pyons. Each of them are 3 Pyons which makes a total of 15 monsters defeated when you kill them all.
  
• Use Serpent's Tongue to kill them in one hit (sometimes it can miss)
  
• When you are done killing the 15 monsters. Rest on the camp site to respawn enemies. You can use Tab to teleport directly to the camp site. Limited to use three times per dungeon. Then you will have to go manually (Maybe use dash with Space Key to move quicker) thankfully the camp site is right next to us.
  
• Rinse and repeat until you get there.

Mythical Strategist

Use 5000 Skills in combat



This is simpler. Get any student or better three students (preferably with high MP (AP) although not necessary) and make them learn the first skill from the Divine Course called Mass Heal. It only consumes 5 MP.

• Select the same region and quest like the other achievement and get into battle. Since the enemies are low level and you barely will take damage from them, you can spam Mass Heal over and over again without doing any damage so you don't kill the monsters.

These two achievements are the most tedious to get in this game since doing both using skills and defeating 5000 monsters are a lot of times. It gets extremely boring so I recommend to do it a bunch of times and continue another day doing it another bunch of times.

So far I don't know if there is any other better and faster way to do this. This is the best way I found myself to do this. I hope this guide helps all of those folks who want to get the 100% of this game!

I hope the guide is clear and if there is anything you want to know, write on the comments section
